I look at this and see the earth is growing in size. These sedimentary layers exists all over the planet. Yet scientists insist the earth is NOT growing in size. (they believe that most of the material burns up in the upper atmosphere) Yet, about 100 hundred tons of meteoritic material (space dust) impacts earth every single DAY. “…Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles…” SOURCE: NASA

NOTE: Scientists believe that most of these particles burn up completely in the upper atmosphere, and that’s what causes meteors; the bright “shooting stars” we see at night). But I don’t think that’s accurate. I think much more material makes it to earth’s surface than scientists currently believe. What one has to understand is this is a GUESS on science’s part on the amount of material that burns up versus how much actually impacts the surface of the earth. This is a subject of great debate, regardless of the general consensus, there are those that think more material reaches earth than is previously thought. Regardless.

“Every year 5,200 tons (4,700 metric tons) of interplanetary dust particles reach the Earth’s surface, a new study reports. These novel findings suggest that cosmic dust is the main source of extraterrestrial material on Earth, far exceeding the input from larger, more visible meteorites, which are considered to bring less than 10 tons (nine metric tons) of material to Earth every year. This information can help scientists understand the role that interplanetary dust played in supplying water and carbonaceous molecules to a young Earth early in our planet’s formation history.” – SOURCE: Space.com

If you looks at what Space.com says at 5200 tons of material actually reaches earth’s surface, versus the total 36,500 tons of space dust falls into earth’s atmosphere, that suggests about 14% of the material does not burn up in the atmosphere and in fact hits the surface of the earth.

I personally think that number is MUCH higher than we think it is. Unfortunately there has never been a study to see how much material of any given size burns up and how much makes it to ground, from grain of sand to automobile, no one really knows that number. It’s ALL speculation and guesses. No one knows, and even if they claim to know, they certainly don’t know.

But for sake of argument, let’s say that 14% number is accurate. That’s 5200 tons of material.

Spread out over the entire surface of the planet, if a portion of that material does in fact reach earth’ surface, that explains the layers very nicely. It’s not much per year. Maybe about .1mm (according to a study done back in 2011).

But over time…millions of years, this forms layers. Imagine a jawbreaker candy. Or a pearl. It starts out small. But then accretes material over a very long period of time. Given enough time and material, that spherical candy or pearl will grow to a very large size. So why is it, that scientists cannot agree that earth continues to GROW in size.

I ran the numbers once and it’s staggering how much larger the earth is now, versus its size many billions of years ago.

The amount of space dust that lands on earth’s surface is about .1mm annually. If you assume this “growth” is consistently average around that 0.1mm thickness annually.

That equates to:

1mm every 10 years
10mm every 100 years
100mm every 1000 years
1000mm (1 meter) 10k years

1 meter every 10k years!

Go back to 200k years ago, when modern humans emerged, and we’re looking at about 20 meters of growth since humans have been on earth.

20 meters! That’s about 65.6 feet deep.

But that’s only 200k years.

Add another 800k to make it an even 1 million years. And that’s about 100 meters, or about 328 feet per million years.

All this of course assumes that the “insignificant” .1mm growth happens consistently throughout time and that is being used as an average.

I don’t know about you, but 100 meters every 1 million years is considerable.

There are 1000 million in a billion years.

100k meters per billion years.

That’s 100 kilometers deep!

The earth’s crust is only 5–70 kilometers deep according to the current science.

But due to the oceans and tectonic plates, geological migration of entire continents etc.. the earth’s crust ‘floats’ on the mantle which over time acts as a viscous substrate/liquid. It’s a fluid dynamics thing.

Anyway…this suggests that anything older than 700 million years or so would be pushed down into the upper mantle and melted away, but because of plate tectonics, and their constant up and down movement, some rock that is billions of years old is nearer the surface of the earth, giving us access to how the earth was billions of years ago.

I find this fascinating and intriguing. Hypothetically speaking, there could have been a lost technologically advanced civilization billions of years ago. Not likely, but it’s possible. We would have found evidence of such a civilization by now…right?

Yeah…I’m not so sure. Given the total amount of surface area, and logistics, and money involved in cost to research and there’s just not enough geologists and archeologists in the world to cover in detail the entire surface, much less what’s buried beneath it.

When you factor in weathering, and oxidation, and tectonic movements, and volcanic activity, ice ages, the movement of entire mountain ranges and the erosion and desintegration of iron, steel, and other things we have now, there’s just no way to tell.

Think about it this way. Look 1 billion years into the future. Let’s say we destroyed ourselves with nuclear weapons causing a nuclear winter and destroying all living things on the planet. Humans would become extinct.

A billion years from now all that evidence of our existence would be gone. Eroded away, and buried beneath 100 kilometers of earth.

All our civilizations. All the evidence of our civilization would essentially evaporate and erode away into the ether. There would be nothing left to discover. No evidence of our existence.

That is a sobering thought.
